Embodiment 1

[0059] like figure 1 As shown, the present invention provides a sample head 100 for taking a coal sample, the sample head 100 includes a sample tube 110, and both ends of the sampling tube 110 rotate with multiple bass 140, when the sample head is in the first In the state, the baht 140 encloses both ends of the sampling tube 110 to enclose the plurality of impartial tabs 140 to the sample tube 110 into a sample chamber 120, and the sample cavity 120 is used to collect coal samples, and both ends of the sample cavity 120 are in the external environment. Connect. With both ends of the two ends, the sampled head 100 can cause the sampling head 100 to enter the sample cavity 120, and thereby avoiding the case of mixing the surface of the surface coal in the sample cavity 120 to avoid sampling accuracy. The sampled head 100 can be achieved by using the onset 140 to open or close the sample cavity 120, and the sample head 100 can be achieved in a predetermined sampling position to be t...

Embodiment 2

[0072] like Figure 4 As shown, the present invention also provides another sampled head 100 for adopting a coal sample, and the sample head 100 includes an inner cylinder 150 and an outer cylinder 160 in the inner cylinder 150, and the inner cylinder 150 is convex The tapered member 153 is provided, and the outer cylinder 160 is rotated to the inner cylinder 150, and the inner cylinder 150 is provided with inner cylindrical cavity 151 for collecting the coal sample, and the inner cylinder 150 is opened in the inner cylinder of inner cylindrical cavity 151. The body hole 152, the outer cylinder 160 is opened, and when the outer cylinder hole 161 communicates with the inner cylinder hole 152, the inner cylindrical cavity 151 is opened / closed. The outer cylinder hole 161 can communicate / partition the outer cylinder hole 161 and the inner cylinder hole 152 by the inner cylinder 150 and the outer cylinder 160, thereby opening / closing the inner cylindrical cavity 151, the above-de...

Abstract

The invention relates to the technical field of coal sample quality inspection, and particularly discloses a coal sampling method and a sampling vehicle. The method is used for sampling a coal pile, and comprises the following steps of acquiring the morphology of the coal pile, and determining the volume of the coal pile, calculating the weight of the coal pile by using the density of the coal pile, determining sampling units according to the weight of the coal pile, and acquiring coordinates of a plurality of subsample collection areas in each sampling unit, moving the sampling vehicle to a position near a sub-sample collection area, enabling the shooting device to shoot a coal pile located in the sub-sample collection area, enabling the sampling head to sample a coal sample corresponding to the subsample collection area, and enabling the shooting device to shoot the coal pile located in the subsample collection area again. By means of the arrangement, sampling efficiency, sampling precision and field adaptability can be improved, labor cost is reduced, and interference of human factors is avoided. By means of the lifting arm and the manipulator on the sampling vehicle, the flexibility of the sampling head can be improved, and the sampling position of the sampling head can be conveniently selected.

Description

Technical field [0001] The present invention relates to the technical field of coal samples, and more particularly to a coal sampling method and a sample vehicle. Background technique [0002] Coal analysis is the basis of coal utilization. Coal sampling is the premise of coal analysis. The purpose of coal sampling is to obtain a consolidated coal sample that is constructed and characterized by sample coal, or said that its test results can be sampled. Test coal samples for composition and characteristics. The basic principle of sampling is that all particles of sampled coal can enter the sampling apparatus, each having equal probability of samples. Coal sampling must truthfully, representative, and must determine the sampling method, the number of sampling, and the like, according to a certain sampling standard. [0003] Coal sampling path can be divided into: a. Take a sore from the drop coal flow of the belt conveyor unloading point; b. Sampling from the mobile coal flow of th...
